The irreducible epistemic atoms underlying the curriculum. 4,828 atoms across 8 types and 2 molecules
Conversational memory: the cognitive process by which information exchanged during social interactions is encoded, stored, and retrieved, characterized by systematic forgetting patterns, gist-based recall, and source monitoring failures that make it particularly unreliable for decision-making
Third brain: the externalized cognitive infrastructure that extends human mental capabilities through tools, systems, and artifacts that enable information processing, storage, retrieval, and integration beyond the biological limitations of individual cognition
Emotion: a somatic marker that represents a brain's prediction about what bodily sensations mean in the current context, based on prior experience and learned categories, serving as essential data for decision-making rather than noise interfering with rational thought
Surprise: the neurochemical signal generated by prediction error when reality differs from expectation, serving as the primary learning trigger in biological systems and indicating a gap between one's internal model and external reality
Decision journal: a structured record of decisions that captures not just what was decided but why, including the reasoning, expected outcomes, and review dates, designed to preserve the actual decision-making process before hindsight bias can contaminate memory
Attention: the finite cognitive resource that supports sustained directed focus and deliberate reasoning, which depletes with use across all acts of executive function and cannot be restored through willpower alone, requiring specific recovery conditions including rest, nature exposure, or low-demand automatic processing
Attention allocation: the continuous series of decisions to maintain task-positive engagement against the gravitational pull of default mode, where every act of attending to one thing is simultaneously an act of ignoring everything else
Attention management: the ability to choose where you direct your attention in any given moment, distinguished from time management which focuses on fitting more into schedule rather than ensuring cognitive presence
Opportunity cost: the value of the best alternative you gave up by making a choice, specifically in attention terms measuring what you would have produced with that attention had you spent it on your most important work
Context switching: the cognitive process of shifting attention from one task to another that incurs a measurable recovery tax of 10-25 minutes of degraded cognition due to task-set reconfiguration, transient carry-over, and reconfiguration time, with the cost being invisible because the brain continues to run previous task threads while attempting new tasks
Attention follows intention: the cognitive process where deliberate pre-decision about focus direction causes the perceptual system to reorganize around that decision, filtering and prioritizing information while suppressing distractions
Reactive attention: the default cognitive state where attention scatters to the most salient environmental stimulus because no explicit intention has been declared to bias attention toward specific information
Environment: the physical and digital workspace that actively participates in cognitive processing by competing for neural resources, shaping attention through affordances, and functioning as a component of cognition rather than just a context
Notification: a digital interrupt that claims attention through engineered design patterns, creating conditioned responses and producing measurable cognitive costs including task resumption delays and attention residue, with each notification representing a tax on cognitive resources
Affordance: the possibilities for action that an environment offers to an organism, existing in the relationship between environment and organism rather than as properties of objects or people alone, and functioning as invitations that influence behavior before conscious decision-making
Boredom: the aversive experience of wanting, but being unable, to engage in satisfying activity
Time-boxing: the practice of setting a fixed temporal boundary for a task or activity to create a container that sharpens focus, prevents task expansion, and enables sustained attention within defined limits
Soft fascination: the type of environmental stimulation that gently holds involuntary attention without demanding cognitive engagement, allowing directed attention to rest and recover
Micro-break: a brief pause of 10 minutes or less taken during work to preserve attentional capacity and prevent directed attention fatigue
Attention scaffolding: the environmental rituals, spatial configurations, temporal commitments, and procedural routines that make deep work the default rather than the exception
Deep work: professional activities performed in a state of distraction-free concentration that push cognitive capabilities to their limit, creating new value and improving skill through sustained focus on a single problem space
Grand gesture: a dramatic change to your environment or a significant investment of money, effort, or commitment that raises the psychological stakes of a deep work session so high that procrastination becomes irrational
Shutdown ritual: a brief end-of-day procedure that creates a clean cognitive boundary between work and rest and closes attention residue from unfinished tasks
Attention debt: a cognitive deficit that accumulates through chronic attention splitting and manifests as exhaustion, poor judgment, and degraded cognitive performance, which compounds over time and cannot be perceived from within the depleted state
